HAN D-STAM P.

SPECIFICATION forming part of Letters Patent No. 232,145, dated September 14, 1880.-

Application filed June 21, 1880. (No model.)

To all whom it may concern:

Be it known that I, LORENZO POTTER, of Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in Hand-Stamps; and I hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which my invention appertains to make and use the same, ref erence being had to the accompanying drawin gs, forming a part hereof, and in which- Figure 1 represents a side elevation, the right-hand half of which is shown in vertical central section. Fig. 2 represents a plan view of the same with the right-hand half of the frame removed, and showing the inking pad or wheel and its actuating mechanism in full. Fig. 3 represents an inside view of the leg I).

Like letters of reference indicate like parts.

My invention relates to that class of handstamps provided with a revolving or tumbling type-plate, in which the type receives the impression from the inking-pad secured to the upper part of a stationary frame, over which plays a reciprocating frame which carries, and also by its vibration causes, the type alternately to come in contact with the inkingpad and paper 5 and it consists in providing a hand-stamp of said description with a revolving ink-pad, substantially as hereinafter described.

As heretofore constructed said inking-pad has been fixed so that the type would always strike it in the same place, which soon wore away the inking-surface, so that it had to be renewed frequently, and also thereby caused the type to wear unevenly, so that it soon failed to make a clear and distinct impression; and to overcome the said imperfection I construct my hand-stamp as follows.

In the drawings, (i represents the stationary frame; b, the reciprocating frame; f, the tumbling type-plate; l, the pivot on which the type-plate turns, and which also holds the parts a and I) together; a, the type affixed to plate f d, the revolving ink-pad, provided with ratchet-teeth g,- h, the ratchet-bar, provided with a spur, 8, one end of which plays loosely on the center k,- k, the center or pin upon which the inking-pad (1 turns; 6, a pin affixed to the free end of the ratchet-bar, and c a diagonal slot in one of the legs b of the reciprocating frame I).

The operation of my improved hand-stamp is as follows: When the'framc b is pressed downward to bring the type c in contact with the paper, the plate fis caused to turn or make a half-revolution by well-known mechanism attached to and forming a pal-tot the frame a. (Not here shown.) As the frame 1) passes downward the pin 'i of bar It, playing in the socket c, reciprocates back and forth in a plane with that of the inkingpad (I, and thus the bar 71, being actuated thereby, engages, with its spur s, with the teeth 9 of the inkingpad (I, and causes it to turn 'and present a new surface to the type at every impression.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a hand-stamp, the combination of the stationary frame a, reciprocating frame I), and revolving inkingpad (I, provided with the ratchet g, with the actuating ratchet-bar h, leg 1/, provided with the diagonal slot 0, and tumbling type-platef, substantially as shown and described.

2. In a hand-stamp, the revolving inkingpad (1, provided with ratehets g, in combination with the actuating ratchet-bar h and leg I), provided with the diagonal slot a, substantially as and for the purpose specified.

LORENZO POTTER.
